FAQ of Vertical Multistage Centrifugal Pump of QDLF Series

1. How can I get trained on CNBM products?

Yes, we provide training courses in our factory (products, general and specific pump technology, hydraulics, and practical applications). Please consult your sales manager or get in touch with our headquarters for more information.

2. Are your pumps cheaper than those of your competitors?

CNBM aims to give its customers the highest standards of quality and service and delivery times, all at a reasonable price.

3. Do you have self-priming pumps?

Yes, our product portfolio also includes two ranges of self-priming pumps: self-priming electric pumps and self-priming side channel pumps.

4. Is it really necessary to fit a bleed valve for the boxes?

It is always best to have a bleed valve as the gas produced by the fermenting sewage is potentially hazardous.

Q:model # gg9002b serial # 65x626092 what year is it and what is the water pump number: www.okorder /

Q:What's the submersible pump?: Centrifugal pump, a general motor and pump body is one, you can pump the whole pump into the water

Q:im attaching a motor from another filter onto my homemade filter. but i dont want to have to run a cord all the way from the pond to a powerplug. does anyone know of another way to such water into a filter without using electricity? some kind of siphon?: 1. I had an electrician put a buried cable in the ground coming up to a weatherproof post with outlets and an on-off switch. It was not as expensive as I thought it would be. 2. You can put the water pump and filters by the house or even inside and run buried water pipes out to the pond, or just put the pump inside and have the filter by the pond which would run by water pressure or gravity. 3. A windmill or solar panel. A siphon uses potential energy stored in the water to work. Once the water has dropped through the siphon, there is no more energy to draw from and the siphon stops. A windmill or solar panel could provide the power to lift the water back up and make the process continuous, or at least while it's windy or sunny. However when pricing these two options even though they would be very cool if you have the large yard to accommodate them, they turn out to cost much more than either 1. or 2. and have much higher maintenance costs associated with them. 4. If it's a very small pond, you can get a solar powered filter/fountain that looks like a floating plastic lily pad. My son had one of these, but it only worked on the sunniest of days, and lasted one summer before wearing out. If you add a large block of filter foam over the intake it may last a little longer. Rinse it out two or three times a week.

Q:What is called soft start of water pump?: Close the outlet valve of the pump, open the inlet valve, and can ensure that the water pump "self filling" (the liquid level is higher than the pump inlet pipe under the condition of the water pump start procedure is: to start the motor, to the normal operation of the motor, slowly open the outlet valve, the current gradually increase. But in the unattended operation (valve), and automatically pump, and pipeline diameter and length (in the pipeline water quality will be great), such as the motor start fast, to quickly promote the quality of water (as the train will soon accelerate acceleration), will make the motor starting current is large, causing the motor to trip and the damage of mechanical and electrical. Soft start (soft starter added in the circuit) - that is, slow motor speed, can overcome the above situation.Stop the pump normal order is: close the outlet valve, then stop the motor, such as unmanned operation, the outlet valve is not closed, when the pump stops suddenly, the water inside the tubes (especially vertical pipe), water will quickly turn back, so when the check valve suddenly closed, the fast flowing water suddenly stop by the inertial impact that produces "water hammer" effect and damage of pipeline system, using the "soft stop" should, in the circuit is connected with the soft stop device.

Q:Hi, I need a 12/24v dc submersible water pump that can pump up to 15m but I can't seem to find it anywhere. Any help would be more than appreciated!: in okorder okorder

Q:I REPLACED MY WATER PUMP ON MY 1988 CHEROKEE,THE NEW PUMP STARTED MAKING THE SAME BEARING NOISE.: if it is not anything else making the noise then perhaps you have a defective pump....if that jeep has a 4.0 with a manual tensioner then it is very easy to overtighten the belt and cause pre mature failure of the front bearing in the water pump

Q:Where is the water pump?How do i take it out, and replace it?: Drain Cooling System. Remove right front lower fender shield. Loosen pump pulley bolts Remove Accessory Drive Belt. Remove pump pulley bolts and remove pulley. Remove pump mounting screws Remove pump. Remove and discard O-ring seal. Clean O-ring groove and O-ring surfaces on pump and chain case cover. Take care not to scratch or gouge sealing surface. Reassemble in the opposite order. This will be a good time to replace your thermostat and check all hoses for wear and leaks.

Q:1997 Chevy Cavalier, 2.2 engine. In the past 2 days I noticed that my temp gauge was reading a little higher than usual but not in the danger range. I checked and nedded to add coolant. Last night it started making a chattering or maybe klunking sound. As far as I could tell it was coming from the water pump but it stopped before I could get out of the car and look to see. Now the coolant is low again. Are these signs of the water pump being bad or could it be something else?: It is possible your water pump is worn out, yes...but it could be other things too. I would change the thermostat first, being a much lower cost. If the thermostat is sticking shut, or not opening right at all, it can prevent the coolant from circulating right. That lets the whole engine heat up and coolant boil. That may be the sound you hear, normally called a water hammer... If you take it to the shop, which you should do now, ask them to check the thermostat and water pump, to be certain of the problem... I hope it is just the thermostat that is causing this, but check it good...

Q:My family has a vacation home on the bay side of a small island off the coast of Texas. The house has a water well and uses an electric pump housed in a pump house underneath the structure, which is up on stilts. The house is infrequently used and with the seaside conditions the pump has corroded and will not start automatically. What do I need to do to clean it up so it will function? I do not believe that the motor is damaged.: the problem with the pump not running will be the motor only.....most likely the motor rotor has rusted to the winding core of the motor ....soak it down with wd40 on the inside ...should be vent holes to spray wd40 in...try to find some way to turn rotor ....on some pumps there is a screwdriver slot on the end of the motor...if it still wont run take it to shop

Q:i have an 80' water well with an electric jet pump. is there an electric/manual water pump? i want to be able to have a hand pump attached to the electric pump, so i can still use water when the electricity goes out.: Maybe you have to drill a sperate well.
